Outline of Final Research Achievements |
From the results of screening of own chemical library (including about 200 samples) using both YUCCA enzyme inhibition test (in vitro) and plant growth test with Arabidopsis seeds (in vivo), it was found that several extracts from the red algal genus Laurencia and sea hares, together with 2-APB known as a TRP channel inhibitor, exhibited strong inhibitory effects. Bioassay-guided fractionation of these active extracts resulted in the isolation of three halogenated laurane-type sesquiterpenes with different chemical structures from known YUCCA inhibitors. Among these active compounds, laurinterol and 2-APB showed stronger inhibitory activity than known inhibitors in the plant growth inhibition assay.
